The GICON® Process offers many advantages for plant operators

GICON, together with the Brandenburg Technical University – Cottbus (Germany), has developed a new biogas process through intensive research and has internationally patented it. The GICON® Process is specially designed for wastes with high levels of impurities as feedstock. Thus, both organic and household wastes, impurity-laden solids and green wastes, and agricultural substrates such as energy crops or solid manure can be processed.

Recognized and proven in practice

In 2013, the process was awarded the Saxony Innovation Award and the Saxony Environmental Award. In practice, it has already proved its efficacy. The first and largest high solids anaerobic digestion biogas plant on an industrial scale in North America employed the GICON® Process and has been successfully in operation since 2013. At GICON’s research and development center in Cottbus, Germany, the process is continuously optimized.

The GICON® Process offers many advantages in comparison with conventional methods:

  • Controllability of biogas production
  • Methane content of 15-20% higher than for conventional systems
  • High process stability
  • High availability and safe operation
  • Flexible use of feedstocks due to robustness against impurities
  • Simplified feedstock handling
  • No inoculation of digestate, therefore low risk of silting
  • Low energy consumption
  • Compact design
  • Low risk of encrustation in pipes and aggregates
  • Structurally-rich digestate, low treatment cost for post-processing
